iRule config to Rewrite SSL Header for Transactions

We need to pull three values out of the Client SSL and put them in the Server SSL. Currently we tried using a rule that creates a Session Table to store these. Since this is a API and not a web page we are having timeout issues. Any suggestions on rewriting this would help.

This is part of what we are using.

when CLIENTSSL_CLIENTCERT {

Check if client presented at least one cert if {[SSL::cert count] > 0}{

   Insert the following fields in the session table with a timeout of 7200 seconds:
     Do the processing now as opposed to in HTTP_REQUEST as there
     can be many HTTP requests using the same SSL session ID
  
     Index - item
     1 - serial number of the cert
     2 - issuer of the cert
     3 - subject of the cert
  session add ssl [SSL::sessionid] [list \
     [SSL::verify_result] \
     [X509::serial_number [SSL::cert 0]] \
     [X509::issuer [SSL::cert 0]] \
     [X509::subject [SSL::cert 0]] \
  ] 7200

  log local0. "[IP::client_addr]:[TCP::client_port]: Added session data for cert. Status:\
     [X509::verify_cert_error_string [lindex [session lookup ssl [SSL::sessionid]] 0]] with key [SSL::sessionid]"

} }
